A mixer device 1 includes: a drum 3 configured to store materials to be mixed; a device body 4 configured to rotatably support the drum 3; an electric motor 6 configured to apply a rotational driving force to the drum 3; and a battery 8 configured to supply electric power to the electric motor 6, wherein a wheel 29 is attached to the device body 4, and the battery 8 is arranged above the wheel 29.

A multi-axis mixing apparatus is disclosed that includes a housing and a controller operatively connected to a first motor and a second motor. The apparatus includes a frame supporting the first motor configured to selectively rotate a rotatable assembly. The rotatable assembly supports and provides an operative connection to the second motor configured to selectively rotate a rotatable sub-assembly. The rotatable sub-assembly includes a mechanism configured to receive and hold a container containing contents to be mixed, and the controller is configured to independently operate the first and second motors to mix the contents.

A dispensing container and adapter system for use with a planetary mixer is disclosed. The dispensing container has a longitudinal axis and a transverse axis. The dispensing container may include a nozzle and a removable cap to cover the nozzle. The removable cap may have a first width dimension measured along the transverse axis. The dispensing container may include a body having a second width dimension measured along the transverse axis. An adapter may receive the dispensing container. The adapter may include a cavity to receive the removable cap. The cavity may have a cavity width that exceeds the first width dimension. The adapter may also include a recess for receiving a portion of the dispensing container. The recess may extend from the cavity. At least a portion of the recess may have a width dimension smaller than both the first width dimension and the second width dimension.

Described herein are novel construction materials and construction material compositions, processes, and equipment for manufacturing press-formed biocement and bioconcrete products and construction materials. In some embodiments, the methods include combining aggregate particles with a first measured dose of at least one biological organism or enzyme and a first measured dose of cementation reagents in a first mixer, mixing the contents of the first mixer and reacting the first measured dose of the cementation reagents in the presence of the first measured dose of the at least one biological organism or enzyme to form a biocement which binds to the surfaces of the aggregate particles, thereby increasing the size of the particles to yield a biocement coated aggregate.

Method and equipment for conditioning wet concrete (703), the wet concrete (703) being agitated in a revolving-drum concrete mixer (702), thereby bringing changing portions of the wet concrete (703) to a free surface (706) of the wet concrete (703) inside the mixer (702), the agitated wet concrete (703) being cooled and partially carbonated in that liquid and/or solid carbon dioxide is supplied to the concrete mixer (702) simultaneously with liquid nitrogen so that both the supplied nitrogen and the supplied carbon dioxide contact the free surface (706) of the wet concrete (703).

A rotatable drum system includes a frame and a drum rotationally supported thereon. Paddles in an interior of the drum are angularly offset from the longitudinal axis. An eccentric opening offset from the longitudinal axis forms the egress. Mixed solid waste agitated by the paddles while in the drum. Trunnions may support the drum. An actuator may be pivotable with an upper frame relative to a lower frame and the actuator can cause drum rotation irrespective of a position of the upper frame relative to the lower frame. A trunnion assembly with a rocker pivotally coupled to a base thereof via a first axle, enables the rocker to be pivotable relative to the base about the first axle. A second axle may be rotationally coupled to the rocker. A roller may be rotationally coupled to the rocker via the second axle, and configured to support a rotating load.

A dust generation apparatus is disclosed. The dust generation apparatus includes: a drum defining a drum chamber for receiving a sample; an agitation system in the drum chamber for agitating the sample to generate an aerosol of the sample in the drum chamber, the agitation system including: at least one first agitator rotatably mounted about a rotational axis extending through the drum chamber to stir the sample in the drum chamber; and a plurality of second agitators configured to tumble in the drum chamber during rotation of the at least one first agitator.
